Gov lock rear end

[murdockspencer]

I've got what looks like a gov lock rear in my suburban. Is this a factory Chevy thing? Has anyone had any experience with them? Thanks

Is there any way to tell if you have it without openingup the rear? Codes, etc?

Look for "G80" on the sticker in the glovebox. I have a G80 14 bolt FF and the locker works good on flat ground like in the mud, but if I get it on an angle like in a ditch it won't lock in.

but sticker only be accurate if axle never been swapped or changed internally, so unless youve known the truck since it was brand new then good luck

better open it up to be sure, no way around it really

plus it needs new gear oil anyways

and you wont have to fudge wth the stupid fill plug to refill the diff if you do it with axle out from under truck



good luck

Thats the truth!! Always change the fluid!! The diffs are SO overlooked.

I use gov locs in NORMAL street driven trucks, But they don't take abuse well. If your do any kind of wheeling with it, I'de consider something better.

HAHA, yeah. I mean they don't need much attention, but you wouldn't not belive the people who just drive until it won't move anymore.

I recently had to replace mine due to a heavy foot on wet pavement. It sounded like a bomb went off when it locked. It broke the carrier completely in half.
